DETAILED DESCRIPTION

Embodiments described herein are related to a solar panel guard system.

In the solar panel industry, animal and debris intrusions negatively affect the long-term functionality of solar panel systems. Animals (e.g., squirrels, chipmunks, birds, etc.) can damage components of solar panel systems which are costly to repair. Because solar panels are often mounted to the roofs of homes and buildings, animals and debris are able to enter the space between the solar panel and the roof of the building. Animals that get into the space under the solar panels may construct nests, bringing in foreign material which may pose a significant fire hazard, or otherwise damage the roof of the structure the solar panel is mounted to. Additionally, if birds construct their nest under the solar panels, the increased bird presence around the solar panels tends to result in a large amount of bird droppings on the solar panels which affects efficiency of the solar panel. Squirrels and other rodents also chew on exposed wires under solar panels. With enough chewing, the exposed wires will become permanently damaged, requiring costly repair or replacement.

Conventional systems to combat animal and debris intrusion into the space under solar panels or solar panel arrays include a flexible physical barrier which animals can easily push under. Even when mounted as designed, these conventional flexible physical barriers are not sufficiently rigid to keep animals from pushing under the flexible physical barrier at locations midway between mounting points. Additionally, conventional flexible physical barriers are not durable over time. Conventional flexible physical barriers are subject to damage from squirrels or other rodents chewing on the flexible physical barriers, which permanently damages the flexible physical barrier and allows animals to enter the solar panels.

Some conventional systems use a plastic clip to attach the flexible physical barrier to the solar panels. Over time, the plastic clips fall off the solar panel due to weather, snow build-up, or other natural forces, allowing animals to enter the space under the solar panels. Some plastic clips of conventional systems are damaged by the temperature changes that occur over the course of the seasons. These plastic clips fatigue and break, no longer support the flexible physical barrier, and thereby allowing animal and debris intrusions.

Some conventional systems use adhesives to fasten the flexible physical barrier to the sides of the solar panel. Adhesives break down over time. Adhesives do not provide the strength to be effective at securing the flexible physical barrier which keeps animals and debris from intruding. Conventional systems using adhesive cannot be removed and re-attached.

The devices, systems, and methods disclosed herein provide a solar panel guard system that prevents animals and debris from entering the space under a solar panel. The solar panel guard system may include a bracket (e.g., metal bracket) having a clip disposed at a first distal end of the bracket, where the clip facilitates fastening the bracket to the lip of the solar panel. The clip may be configured to removably attach to the solar panel. The clip may be a clip structure. The bracket may also include a leg extending from the clip. The leg may be a leg structure (e.g., the clip structure and the leg structure may be part of the same structure or may be separate structures). The leg of the bracket may include one or more points of attachment for one or more fastening devices (e.g., fasteners). The points of attachment may be protruding components of the leg. In one embodiment, one or more protruding components protrude substantially perpendicularly from the leg and each is configured to accept a corresponding fastening device. A first protruding component may be closer to the clip end (e.g., first distal end of the bracket) and a second protruding component may be closer to the second distal end of the bracket (e.g., distal end of the leg), opposite the clip. A guard structure (e.g., rigid sheathing, rigid metal sheathing, perforated guard structure, perforated barrier, perforated metal, plastic mesh, wire mesh, screen, and/or the like) may be attached to one or more brackets of the solar panel guard system. The one or more brackets may be attached to a solar panel or a solar panel array. The protruding components may facilitate fastening the guard structure to the bracket.

In some embodiments, the bracket is constructed of one or more of a metal, ceramic, plastic, or durable material. The bracket may have more strength and rigidity than conventional systems for combating animal and debris intrusions into the space under solar panels. The bracket may also be more resilient to weather and temperature changes, and may hold up better over time when compared to other brackets used in similar applications. Constructing the bracket of a durable material (e.g., metal) also gives the bracket more strength which allows the bracket to hold a heavier and stronger guard structure (e.g., sheathing material) to better prevent animal and debris intrusions into the space under a solar panel.

The systems, devices, and methods disclosed herein have advantages over conventional systems. The guard structure of the present disclosure may be more rigid and may prevent animals from pushing under the guard structure as animals can with conventional systems. The guard structure of the present disclosure may provide rigidity over the entire span of the guard structure between brackets to which the guard structure is fastened compared to conventional systems that are less rigid, so animals can push under conventional systems at the mid-points between mounting brackets. The guard structure of the present disclosure may be more durable over time compared to conventional systems. The guard structure of the present disclosure may also have the advantage of being self-securing where the guard structure may be secured to a lip of a solar panel (without fasteners securing the guard structure directly to the solar panel) by the guard structure extending above a bottom surface of the solar panel to prevent the bracket from disengaging from the lip of the solar panel.

FIG. 1A is a schematic diagram illustrating an exploded side view of a solar panel guard system 100, according to certain embodiments. Solar panel guard system 100 may include a bracket 110. The bracket 110 may removably attach to a solar panel (e.g., see FIG. 9). In some embodiments, the bracket 110 may attach to an underside (e.g., lip on the underside) of a solar panel.

Bracket 110 may be made of a rigid material. In some embodiments, bracket 110 is made of metal. In some embodiments, bracket 110 is made of spring steel (e.g., low-alloy manganese, medium-carbon steel, high-carbon steel). Bracket 110 may be made of an alloy of steel having a high yield strength (e.g., 60-220 kilopounds per square inch (ksi)). In some embodiments, bracket 110 is made of aluminum. In other embodiments, bracket 110 is made of plastic. In some embodiments, bracket 110 is made of a temperature resistant plastic. Bracket 110 may be made of a ultra-violet (UV) resistant plastic.

The bracket 110 of the solar panel guard system 100 may include a clip 120. The clip may be a clip structure. Clip 120 may be disposed at a first distal end of bracket 110. Clip 120 may facilitate removably attaching bracket 110 to a solar panel (e.g., clip 120 may be configured to removably attach to a solar panel). Clip 120 may attach to a lip of a solar panel. A lip of a solar panel may be a portion (e.g., structure, ledge, etc.) of a solar panel disposed under the top surface of the solar panel. In some embodiments, clip 120 attaches to a lower lip of a solar panel.

Clip 120 may provide a squeezing or clamping force on the solar panel. At least a portion of clip 120 may elastically deform when bracket 110 is installed on a solar panel. The elastic deformation of at least a portion of clip 120 may provide a clamping force. The clamping force on the solar panel may create a squeezing force which may hold the clip 120 on the lip of the solar panel to which the bracket 110 may be installed. Clip 120 may squeeze the lip of the solar panel to which the bracket 110 may be installed. Clip 120 may be flexible. In some embodiments, clip 120 may be resilient to deformation caused by outside forces such as pushing by animals.

One or more inside surfaces of clip 120 may include protrusions (e.g., teeth, coating, etc.) to provide a friction fit with the lip of the solar panel. One or more inside surfaces of clip 120 may be lined with a rubber or rubberized coating. The rubber or rubberized coating may increase a grip of clip 120 on the lip of the solar panel to retain the bracket 110 in a position on the solar panel. In some embodiments, clip 120 includes a fastener which protrudes through at least one surface of clip 120 to secure the clip 120 to the solar panel (e.g., see FIGS. 4A-B and 5A-B). The fastener may be a screw.

The bracket 110 of the solar panel guard system 100 may include a leg 130. The leg 130 may be a leg structure. Leg 130 may extend from clip 120 to a second distal end of bracket 110. In some embodiments, leg 130 is oriented substantially perpendicular to clip 120 (e.g., see FIGS. 1A-B). When bracket 110 is removably attached to a solar panel, leg 130 may extend substantially downward from clip 120. In some embodiments, leg 130 extends toward a surface disposed under the solar panel. The surface disposed under the solar panel may be a roof of a structure to which the solar panel is mounted. Leg 130 may be sufficiently rigid to resist bending moments caused by an animal pushing on or under leg 130. Leg 130 may be configured to support a guard structure 150.

Leg 130 may have one or more portions (e.g., protrusion, opening, internal threading, external threading, etc.) configured to couple (e.g., removably attach) to a corresponding fastening device 142 (e.g., bolt, screw, nut, wing nut, etc.). In some embodiments, leg 130 has two portions (i.e., as shown in FIG. 1). In some embodiments, leg 130 has more than two portions. In some embodiments, the one or more portions of the leg 130 face an outward direction. In some embodiments, the one or more portions of the leg 130 face an inward direction. The one or more portions of the leg 130 may include one or more protruding components 140. The one or more protruding components 140 may outwardly protrude substantially perpendicularly from a main body of the leg 130 (e.g., the main body extends from the clip 120 to a distal end of the bracket 110, the clip 120 is oriented substantially perpendicular to the main body of the leg 130, etc.). In some embodiments, the one or more protruding components 140 inwardly protrude from a main body of the leg (i.e., the direction opposite as shown in FIG. 1). The one or more portions of the leg 130 may form one or more openings in the leg 130 (e.g., in the main body of the leg 130, see FIGS. 6A-B). The openings may be holes or channels. The one or more portions of the leg 130 may be threaded. In some embodiments, the one or more portions of the leg 130 are threaded studs (e.g., removably secured to leg 130 or permanently secured to leg 130). In some embodiments, the one or more portions of leg 130 are threaded holes. The threaded holes may include one or more nuts welded to a back side of leg 130 (e.g., see FIG. 6A). In some embodiments, the one or more portions of leg 130 are protruding component 140 a and protruding component 140 b.

Leg 130 may be configured to be extended by an extension structure (e.g., see FIG. 10). The extensions structure may be configured to removably attach to and extend from the second distal end of the bracket. The extension structure may be leg extension 135 (see FIG. 10). In some embodiments, the leg extension 135 attaches to leg 130 and effectively extends the length of bracket 110. The leg extension 135 may be configured to support at least a portion of a guard structure. The leg extension 135 may include one or more portions (e.g., protrusion, opening, internal threading, external threading, etc.) configured to couple (e.g., removably attach) to a corresponding fastening device. The leg extension 135 may include at least protruding component 140 c (see FIG. 10). In some embodiments, the leg extensions 135, together with leg 130, supports guard structure 150.
